TV romance: The duo (pictured in March) met on Season 17 of ABC series The Bachelor and married last year

Earlier this year Catherine came under fire for announcing she was pregnant - via social media alongside a photo of her pushing her belly out - as an April Fool's Day joke.

Some of her followers accused the pretty brunette of being insensitive to women with infertility issues.

The Seattle-born star explained at the time: 'About my earlier post, it was intended to be lighthearted and fun and certainly not insensitive. My heart goes out to all the women struggling with fertility.'

Catherine and born-again virgin Sean abstained from sex until their wedding night.

And Catherine told Us Weekly at The Emmys last year that while the couple were in no rush to have children they were thinking about doing it 'in the next year or so'.

She said: 'We talk about it but we don’t have that light switch that goes on yet. We are cherishing our married life right now without kids but we are excited for when we do.'

They currently star on WEtv’s Marriage Boot Camp: Reality Stars.
